Tuple of three

:+ is a synthetic rune that produces a cell [p q r].

Produces

Twig: [%clls p=twig q=twig r=twig]

Sample

p is a twig. q is a twig. r is a twig.

Tall form

Kingside:

:+  p
  q
r

Queenside:

:+  p  q
r

Wide form

:+(p q r)

Irregular form

undefined

Examples

/~zod/try=> :+  1
              2
            3
[1 2 3]
/~zod/try=> :+(%a ~ 'b')
[%a ~ 'b']

This is the most straightforward case of :+, producing a tuple of four values in both tall and wide form.

/~zod/try=> 
:+  (add 2 4)  (add 2 6)
  |-  (div 4 2)
[6 8 2]

Most commonly :+ helps to organize code, allowing you to produce a cell from nested computation.
